About us
The Fraunhofer Institute for Applied Polymer Research IAP is working on organic electronics, focusing on applications in OLEDs, OTFT, OPV, sensors, and actuators. The main focus is on synthesis of novel materials with improved optoelectronic properties as well as in the device design and manufacture.
Quantum Dots (QDs) are a new class of nanomaterials in which optical properties can be tuned by adjusting the particle size. These unique properties enable QDs to be used in various applications, for example, as luminescent materials in QD-LEDs and displays and as converting material for lighting application. Additionally, environmentally friendly cadmium-free synthesis methods are being explored. Fraunhofer IAP’s concentration is on solution processability which can be manufactured by area or digital printing techniques like inkjet and EHDJet.

Products & Services
Fraunhofer IAP has developed several procedures for the synthesis and modification of QDs and can provide a wide variety of QD-materials. Here, Fraunhofer IAP has developed a method to provide very stable indium phosphide (InP) QDs covering a wide spectral range from green to red with a high quantum yield, low FWHM and high stability in organic and aqueous phases or other matrices. Developing the high-performance QD-LEDs based on InP-based QDs is quite important to bring QD-LEDs into the future market.
Fraunhofer IAP investigated the performance of inverted QD-LEDs fabricated with synthesized multi-shell InP/ZnSe/ZnS QDs and ZnO nanoparticles as well. The results show that InP/ZnSe/ZnS QDs is the most promising candidate for the Cd-free QD-LEDs. The investigated QD-LEDs match the performance of CD-based QD-LEDs with luminance values higher than 25.000 cd/m2.
